The emergence of secure data sharing is already having a tremendous economic impact, in large part due to the increasing ease and safety of sharing financial data. McKinsey predicts that the impact of open financial data will be 1-4.5% of GDP globally by 2030. This indicates there is a narrowing window on a massive opportunity for financial institutions and it is critical that they prioritize data sharing. This session will first address the ways in which Delta Sharing and Unity Catalog on a Databricks Lakehouse architecture provides a simple and open framework for building a Secure Data Sharing platform in the financial services industry. Next we will use a Databricks environment to walk through different use cases for open banking data and secure data sharing, demonstrating how they will be implemented using Delta Sharing, Unity Catalog, and other parts of the Lakehouse platform. The use cases will include examples of new product features such as Databricks to Databricks sharing, change data feed and streaming on Delta Sharing, table/column lineage, and the Delta Sharing Excel plugin to demonstrate state of the art sharing capabilities.

In this session, we will discuss secure data sharing on Databricks Lakehouse and will demonstrate architecture and code for common sharing use cases in the finance industry.

Every year, billions of dollars are lost due to water risks from storms, floods, and droughts. Water data scarcity and excess are issues that risk models cannot overcome, creating a world of uncertainty. Divirod is building a platform of water data by normalizing diverse data sources of varying velocity into one unified data asset. In addition to publicly available third-party datasets, we are rapidly deploying our own IoT sensors. These sensors ingest signals at a rate of about 100,000 messages per hour into preprocessing, signal-processing, analytics, and postprocessing workloads in one spark-streaming pipeline to enable critical real-time decision-making processes. By leveraging streaming architecture, we were able to reduce end-to-end latency from tens of minutes to just a few seconds.

We are leveraging Delta Lake to provide a single query interface across multiple tables of this continuously changing data. This enables data science and analytics workloads to always use the most current and comprehensive information available. In addition to the obvious schema transformations, we implement data quality metrics and datum conversions to provide a trustworthy unified dataset.

The US Army Corps of Engineers (USACE) is responsible for maintaining and improving nearly 12,000 miles of shallow-draft (9'-14') inland and intracoastal waterways, 13,000 miles of deep-draft (14' and greater) coastal channels, and 400 ports, harbors, and turning basins throughout the United States. Because these components of the national waterway network are considered assets to both US commerce and national security, they must be carefully managed to keep marine traffic operating safely and efficiently.

The National DQM Program is tasked with providing USACE a nationally standardized remote monitoring and documentation system across multiple vessel types with timely data access, reporting, dredge certifications, data quality control, and data management. Government systems have often lagged commercial systems in modernization efforts, and the emergence of the cloud and Data Lakehouse Architectures have empowered USACE to successfully move into the modern data era.

Unplanned downtime in manufacturing costs firms up to a trillion dollars annually. Time that materials spend sitting on a production line is lost revenue. Even just 15 hours of downtime a week adds up to over 800 hours of downtime yearly. The use of Internet of Things or IoT devices can cut this time down by providing details of machine metrics. However, IoT predictive maintenance is challenged by the lack of effective, scalable infrastructure and machine learning solutions. IoT data can be the size of multiple terabytes per day and can come in a variety of formats. Furthermore, without any insights and analysis, this data becomes just another table.

The KPMG Databricks IoT Accelerator is a comprehensive solution enabling manufacturing plant operators to have a bird’s eye view of their machines’ health and empowers proactive machine maintenance across their portfolio of IoT devices. The Databricks Accelerator ingests IoT streaming data at scale and implements the Databricks Medallion architecture while leveraging Delta Live Tables to clean and process data. Real time machine learning models are developed from IoT machine measurements and are managed in MLflow. The AI predictions and IoT device readings are compiled in the gold table powering downstream dashboards like Tableau. Dashboards inform machine operators of not only machines’ ailments, but action they can take to mitigate issues before they arise. Operators can see fault history to aid in understanding failure trends, and can filter dashboards by fault type, machine, or specific sensor reading.

Using Databricks, we built a “Unified Talent Solution” backed by a robust data and AI engine for analyzing skills of a combined pool of permanent employees, contractors, part-time employees and vendors, inferring skill gaps, future trends and recommended priority areas to bridge talent gaps, which ultimately greatly improved operational efficiency, transparency, commercial model, and talent experience of our client. We leveraged a variety of ML algorithms such as boosting, neural networks and NLP transformers to provide better AI-driven insights.

One inevitable part of developing these models within a typical DS workflow is iteration. Databricks' end-to-end ML/DS workflow service, MLflow, helped streamline this process by organizing them into experiments that tracked the data used for training/testing, model artifacts, lineage and the corresponding results/metrics. For checking the health of our models using drift detection, bias and explainability techniques, MLflow's deploying, and monitoring services were leveraged extensively.

Our solution built on Databricks platform, simplified ML by defining a data-centric workflow that unified best practices from DevOps, DataOps, and ModelOps. Databricks Feature Store allowed us to productionize our models and features jointly. Insights were done with visually appealing charts and graphs using PowerBI, plotly, matplotlib, that answer business questions most relevant to clients. We built our own advanced custom analytics platform on top of delta lake as Delta’s ACID guarantees allows us to build a real-time reporting app that displays consistent and reliable data - React (for front-end), Structured Streaming for ingesting data from Delta table with live query analytics on real time data ML predictions based on analytics data.

You’ve successfully built your data lakehouse. Congratulations! But what happens when your operational data stores, streaming systems like Apache Kafka or data ingestion systems produce bad data into the lakehouse? Can you be proactive when it comes to preventing bad data from affecting your business? How can you take advantage of automation to ensure that raw data assets become well maintained data products (clear ownership, documentation and sensitivity classification) without requiring people to do redundant work across operational, ingestion and lakehouse systems? How do you get live and historical visibility into your entire data ecosystem (schemas, pipelines, data lineage, models, features and dashboards) within and across your production services, ingestion pipelines and data lakehouse? Data engineers struggle with data quality and data governance issues constantly interrupting their day and limiting their upside impact on the business.

In this talk, we will share how data engineers from our 3K+ strong DataHub community are using DataHub to track lineage, understand data quality, and prevent failures from impacting their important dashboards, ML models and features. The talk will include details of how DataHub extracts lineage automatically from Spark, schema and statistics from Delta Lake and shift-left strategies for developer-led governance.

This presentation will first introduce the use case, which generates the price adjustments based on the network effect, and the corresponding model relies on the 108 near real-time features computed by Flink pipelines with the raw demand and supply events. Here is the simplified computation logic:

-The pipelines need to process the raw real-time events at the rate of 300k/s including both demand and supply -Each event needs to be computed on the geospatial, temporal and other dimensions -Each event contributes to the computation on the original hexagon and the 1K+ neighbours due to the fan-out effect of Kring smooth -Each event contributions to the aggregation on multiple window sizes up to 32 minutes, sliding by 1 minute, or 63 windows in total

Next the presentation will briefly go through the DAG of the Flink pipeline before optimization and the issues we faced: the pipeline could not run stably due to OOM and backpressure. The presentation will discuss how to optimize a streaming pipeline with the generic performance tuning framework, which focuses on three areas: Network, CPU and Memory, and five domains: Parallelism, Partition, Remote Call, Algorithm and Garbage Collector. The presentation will also show some example techniques being applied onto the pipelines by following the performance tuning framework.

Then the presentation will discuss one particular optimization technique: Customized Sliding Window.

Powering machine learning models with near real-time features can be quite challenging, due to computation logic complexity, write throughput, serving SLA, etc. In this talk, we have introduced some of the problems that we faced and our solutions to them, in the hope of aiding our peers in similar use cases.

Microservices is an increasingly popular architecture much loved by application teams, for it allows services to be developed and scaled independently. Data teams, though, often need a centralized repository where all data from different services come together to join and aggregate. The data platform can serve as a single source of company facts, enable near real time analytics, and secure sharing of massive data sets across clouds.

A viable microservices ingestion pattern is Change Data Capture, using AWS Database Migration Services or Debezium. CDC proves to be a scalable solution ideal for stable platforms, but it has several challenges for evolving services: Frequent schema changes, complex, unsupported DDL during migration, and automated deployments are but a few. An event streaming architecture can address these challenges.

Confluent, for example, provides a schema registry service where all services can register their event schemas. Schema registration helps with verifying that the events are being published based on the agreed contracts between data producers and consumers. It also provides a separation between internal service logic and the data consumed downstream. The services write their events to Kafka using the registered schemas with a specific topic based on the type of the event.

Data teams can leverage Spark jobs to ingest Kafka topics into Bronze tables in the Delta Lake. On ingestion, the registered schema from schema registry is used to validate the schema based on the provided version. A merge operation is sometimes called to translate events into final states of the records per business requirements.

Data teams can take advantage of Delta Live Tables on streaming datasets to produce Silver and Gold tables in near real time. Each input data source also has a set of expectations to ensure data quality and business rules. The pipeline allows Engineering and Analytics to collaborate by mixing Python and SQL. The refined data sets are then fed into Auto ML for discovery and baseline modeling.

To expose Gold tables to more consumers, especially non spark users across clouds, data teams can implement Delta Sharing. Recipients can accesses Silver tables from a different cloud and build their own analytics data sets. Analytics teams can also access Gold tables via pandas Delta Sharing client and BI tools.

Apache Kafka is the de facto standard for real-time event streaming, but what do you do if you want to perform user-facing, ad-hoc, real-time analytics too? That's where Apache Pinot comes in.

Apache Pinot is a realtime distributed OLAP datastore, which is used to deliver scalable real time analytics with low latency. It can ingest data from batch data sources (S3, HDFS, Azure Data Lake, Google Cloud Storage) as well as streaming sources such as Kafka. Pinot is used extensively at LinkedIn and Uber to power many analytical applications such as Who Viewed My Profile, Ad Analytics, Talent Analytics, Uber Eats and many more serving 100k+ queries per second while ingesting 1Million+ events per second.

Apache Kafka's highly performant, distributed, fault-tolerant, real-time publish-subscribe messaging platform powers big data solutions at Airbnb, LinkedIn, MailChimp, Netflix, the New York Times, Oracle, PayPal, Pinterest, Spotify, Twitter, Uber, Wikimedia Foundation, and countless other businesses.

Come hear from Neha Power, Founding Engineer at a StarTree and PMC and committer of Apache Pinot, and Karin Wolok, Head of Developer Community at StarTree, on an introduction to both systems and a view of how they work together.

Working with S3 is different from doing so with HDFS: The architecture of the Object store makes the standard Spark file connector inefficient to work with S3.

There is a way to tackle this problem with a message queue for listening to changes in a bucket. What if an additional message queue is not an option and you need to use Spark-streaming? You can use a standard file connector, but you quickly face performance degradation with a number of files in the source path.

We have seen this happen at Hunters, a security operations platform that works with a wide range of data sources.

We want to share a description of the problem and the solution we will open-source. The audience will learn how to configure it and make the best use of it. We will also discuss how to use metadata to boost the performance of discovering new files in the stream and show the use case of utilizing time metadata of CloudTrail to efficiently collect logs for hunting cyber attacks.

Streaming data pipelines can fail due to various reasons. Since the source data, such as Kafka topics, often have limited retention, prolonged job failures can lead to data loss. Thus, streaming jobs need to be backfillable at all times to prevent data loss in case of failures. One solution is to increase the source's retention so that backfilling is simply replaying source streams, but extending Kafka retention is very costly for Netflix's data sizes. Another solution is to utilize source data stored in DWH, commonly known as the Lambda architecture. However, this method introduces significant code duplication, as it requires engineers to maintain a separate equivalent batch job. At Netflix, we have created the Iceberg Source Connector to provide backfilling capabilities to Flink streaming applications. It allows Flink to stream data stored in Apache Iceberg while mirroring Kafka's ordering semantics, enabling us to backfill large-scale stateful Flink pipelines at low retention cost.
